Embodiment:
Pre-buried plastic conduit when inspection chamber is built by laying bricks or stones → the lay equipment of the holding one's breath → air that adds high pressure hold one's breath test → venting and dismounting equipment hold one's breath major equipment and preparation:
1, circularity and the tightness when placing air bag for guaranteeing the inspection chamber pit shaft wanted 0.5 meter of a pre-buried segment length in the inspection chamber pit shaft stage of building by laying bricks or stones, and internal diameter is 0.7 pvc plastic conduit.Adopt the sealing binder that the plastic conduit bottom is bonded together with pit shaft, around plastic tube, lay pit shaft.The pre-buried plastic tube at inspection pit shaft place will install, and excessive pressure is not arranged when building the inspection pit shaft by laying bricks or stones, to prevent the plastic conduit distortion.When holding one's breath experiment, in this plastic pipeline, fill in pressure bladder, can stop to check the not round gas leakage that is brought of pit shaft.Critical piece and installation method are as shown in Figure 1.
2, pressure bladder adopts annular air-pocket, and the pit shaft place gets pumping valve inside and tensimeter are installed on the air bag intermediate plate.
3, inflation and air pressure opertaing device mainly are air compressor machines.
Concrete construction procedure is following:
1, installs after one section (or multistage) inspection chamber builds completion by laying bricks or stones at sewer line, will carry out the leakproofness test by the quality inspection requirement.Earlier inspection chamber and the place that pipeline junction, cover plate installation place etc. leak air are easily checked that range estimation does not have the suspicious points of gas leakage.2, the sealing of the sewer line mouth of pipe: about 0.3 meter of homonymy pipeline opening in adjacent two inspection chambers (in the pipe); Water spray or coat vaseline on tube wall; Pressure bladder is installed, four L shaped claws are stuck on the mouth of pipe, give airbag aeration with air compressor (or using inflator); Be forced into 0.15-0.20MPa, with pipe sealing.Tighten 4 fastening screws on the wheel hub inwall, guarantee that air bag is unshift when pressurization detects.L shaped claw and plastic conduit contact point adopt rubber blanket, to prevent to damage plastic tube.
3, the sealing of sewage inspection well head: in the middle of the plastic conduit in pit shaft, pressure bladder is installed, is given airbag aeration to requiring atmospheric pressure value to good seal with air compressor.Connect the middle valve inside of pit shaft air bag, be inflated to 1.5 atmospheric pressure, see if there is gas leak phenomenon with air compressor machine.If no gas leak phenomenon continues to be pressurized to 3KPa, close gas check valve, air pressure is tended towards stability, air pressure is reduced to 2KPa from 3KPa, must not last less than 5 minutes.Air pressure descends too fast, suitably tonifying Qi, and it is slow to descend, suitably venting.
5, press regulation in the pneumatic test standard scale 2, confirm different holding one's breath the time according to different tube diameters.The minute atmospheric pressure value begins from 2KPa, and the time used when air pressure drops to 1.5KPa must not be less than the regulation of minute in the table 2.
6, the disqualified upon inspection of holding one's breath should carry out leak test, repairing, reinspection.
7, pipeline is held one's breath to check and is finished the gases at high pressure in first discharge line and the inspection chamber, the gas in the vent pipe gas shutoff capsule again.Dismounting equipment, disposal data.
